X Factor winner Louisa Johnson has posted some teasers of her brand new single Best Behaviour.

The 2015 X Factor winner announced the song on Twitter last month as it went up for pre-order, currently set to be made available on Friday.

And over the past 24 hours, Louisa has been tweeting some extracts from the track ahead of its release.

Speaking about the track to this week's OK! magazine, Louisa revealed: "It's very different from So Good and Tears but I think that's interesting. No one would really expect it and it's my favourite song on the whole album.

"I can never sit down and listen to an album that all sounds very similar, so I like to change it up.

"I've met some amazing people, especially songwriters who've written the biggest hits in the world."

The teenager went on to discuss writing her own tracks for her upcoming record, saying: "It's hard to start writing but when you get into the swing of it and you're with the right people, it just flows.

"Don't get me wrong - there are songs on the album I haven't written, but I would never sing a song that doesn't relate to me, ever."

Best Behaviour is the third single from Louisa who has yet to release an album but promised fans her debut record will "definitely" be out in 2017.

Unusually for an X Factor winner, Louisa has still yet to put out her record despite appearing on the show more than a year ago now.

Last year, the champ of the 2015 series collaborated on 'Tears' with Clean Bandit before releasing her solo single 'So Good' which peaked at Number 13 in the charts.

Louisa has revealed a further collaboration with Clean Bandit will appear on her debut album.
